TDA was established in 1988, to offer a professional drawing service to structural engineers. Later we added Structural Design to our scope of services. We provide AutoCAD drawings for all aspects of structural and civil engineering, specialising in Reinforced Concrete.
We have worked in the commercial, residential, educational, recreational and public health sectors. In recent years we have added new areas of expertise, including patent application drawings, technical illustrations, mapping and architectural layouts.
With a skilled team including a Chartered Engineer, Graduate Engineer and several experienced technicians, we can respond quickly to your request, be it for one drawing or to help on a major project.
